An agency user has control over all accounts under the agency. If you would like to just add a user to one account please take a look at how to add an account user.
From your WhatConverts Agency dashboard, select “Settings” from the main navigation and then click on “Users” from the drop-down.
Click on the “Add Agency User” which will bring up a popup to add a user.
Type in the email address of the user you would like to add. Once you add an email address they will be sent an activation email.
